It took me months to build the framework of my dreams. Rust on the back, front fully rendered via native WebGPU, SEO friendly.. Mah! ❤️

15 years ago, I and @pieteromvlee changed design, forever. We're ready to do it again, with something new, starting tomorrow.

Everyone builds these grids with WebGL. including me, normally. So this morning I built a demo one in pure DOM instead. one matrix3d per card, from techniques I've been using for years. Infinite in every direction, domed, cursor lens, flashlight, click-to-open case study. Zero dependencies. Demo link (with claude skill) in comments🙂

My skills repo has gained 8,000 GitHub stars in a week, it surpassed Vaul and is 300 stars short of surpassing Sonner. Not greatest metrics of success, but it’s a good indication of how the times change.

CSS Tip! ⭐️ You can use mix-blend-mode with scoped custom properties to create this inverted :hover effect 🤙 button > span { left: calc(var(--x, 0) * 1px); top: calc(var(--y, 0) * 1px); mix-blend-mode: difference; 👈 } The cool trick is that using mix-blend-mode acts like a color inverter which works well with monochromatic controls 😍 Saves defining the :hover colors, etc. It works it out for you! As for how to move that spot around? A teeny bit of JavaScript 🤏 const UPDATE = ({target, x, y }) => { const bounds = target.getBoundingClientRect() target​.style.setProperty('--x', x - bounds.left) target​.style.setProperty('--y', y - bounds​.top) } const BTNS = document.querySelectorAll('button') BTNS.forEach(BTN => BTN.addEventListener('pointermove', UPDATE)) On :hover you can use a scoped custom property to change the size of the spot button:is(:hover, :focus-visible) { --active: 1; } button span { transform: translate(-50%, -50%) scale(calc(var(--active, 0) * 3); transition: transform 0.25s; } But, what about the bouncy easy? You can use linear() where supported to create a bouncy transition ✨ @​supports (transition-timing-function: linear(0, 1)) { button:is(:hover, :focus-visible) span { transition-duration: 0.5s; transition-timing-function: linear( 0, 0.5007 7.21%, 0.7803 12.29%, ... ); } } That's it! Thanks for the challenge @alemalohe 🤙 @CodePen link below! 👇

Future UI && CSS Tip! 🔮 You could use View Transitions to animate CSS grid position and create an OSX-style exposé for a portfolio 🔥 It's a grid where things move based on state. Wrapped in a VT 🤙 [data-expose] section{ grid-area:var(--x)/var(--y); } @CodePen link below 👇

Simple 3D CSS demo: an interactive version of Friedrich's "Wanderer Above the Sea of Fog." Hover over the image (or tap if on mobile) to see it move. Live demo and source code: alvaromontoro.com/demos/wand… Note: the demo uses :has(), so it won't work on Firefox.

the new experimental animation-timeline (developer.mozilla.org/en-US/…) together with clip-path is a really cool way to create responsive scroll effects #css

I am joining the game and trying the new View Transitions on CSS Tip 👉 css-tip.com 👈 Yes, what you see are Zig-Zag edges 👀 Open your Chrome, activate the "viewTransition" flags and have fun! 🤩 #CSS
Really happy to see stuff like this. It's hard getting feedback on web APIs, and there are few second chances, but it seems like we did ok on this one. Loads more to do to get the MPA bit over the line, but the folks working on it are smart as fuck. They'll do good.
